我正在使用 react-leaflet，到目前为止我的地图显示良好。我也成功地用来<GeoJson>覆盖多边形。

我目前已经硬编码了我的中心和缩放值，但我希望设置我的默认缩放，以便整个 GeoJSON 多边形可见。我正在为我在网上找到的文档/答案而苦苦挣扎（我只是初学者/中级 JS）。

这是我的组件：

import React from 'react';
import { StyleSheet, css } from 'aphrodite/no-important';
import L from 'leaflet';
import { Map, TileLayer, Marker, Popup, GeoJson } from 'react-leaflet';
import axios from 'axios';

const styles = StyleSheet.create({
  map: {
    height: 240,
    width: '100%'
  }
});

更新：

当我使用 React 开发工具时，选择我的<MapHolder>组件，切换到控制台，然后运行

$r.refs.foo.leafletElement.fitBounds($r.refs.geojson.leafletElement.getBounds());

一切都按预期工作。但是，在我的代码中

this.refs.foo.leafletElement.fitBounds(this.refs.geojson.leafletElement.getBounds());

返回Uncaught TypeError: Cannot read property 'leafletElement' of undefined

我好近！我错过了什么？

由于 react-leaflet 处理其生命周期的方式，即在挂载 Map 组件后立即将控制权移交给传单，因此访问子组件引用可能会很棘手。

我通过两种方式解决了这个问题。

我的第一次尝试涉及存储在我的外部组件状态中添加的功能数量，layeradd按照上面的建议附加一个地图对象事件处理程序，然后在添加所有多边形后访问 Geojson ref。

```

componentDidMount() {
   let count = 0;
   const map = this.refs.map.leafletElement;
   map.on('layeradd', () => {
       count += 1;
       if (count > this.state.polygonCount) {
            setTimeout(()=>{DO STUFF}, 200)
        }
   });
}

```

虽然这有效，但它闻起来很香。

我解决这个问题的第二种方法是使用turf-bbox预先计算 geojson 的边界，然后我在我的渲染方法中将其传递给 Map 对象。

```

const bboxArray = bbox(geojson);
const corner1 = [bboxArray[1], bboxArray[0]];
const corner2 = [bboxArray[3], bboxArray[2]];
this.state.bounds = [corner1, corner2];

```

接着

```

 <Map bounds={this.state.bounds} ref="map">

```

如果您不需要对 GeoJSON 传单元素做更多的事情，第二种方法会更干净，但第一种方法可以让您设置任意数量的事件处理程序等。

看起来你已经完成了 99% 的任务！为了未来读者的利益，您可以避免挥之不去的未捕获类型错误：

Uncaught TypeError: Cannot read property 'leafletElement' of undefined

fitBounds...通过将方法调用包装在检查中以确保this.refs.foo,this.refs.geojson和朋友存在：

if (this.refs.foo && this.refs.foo.leafletElement && this.refs.geojson && this.refs.geojson.leafletElement) {
    this.refs.foo.leafletElement.fitBounds(this.refs.geojson.leafletElement.getBounds());
}

当前实现抛出错误的原因是地图和 GeoJSON 参考在render方法被调用一次之前没有设置。这意味着this.refs.foo并this.refs.geojson没有在第一次render调用该方法时设置。

您还可以考虑将整个fitBounds操作移出 render 方法并移入componentWillReceiveProps; geodata如果可能通过发送到地图组件的道具动态更新，这将特别值得。

根据@IvanSanchez 的回复以及 react-leaflet 的工作原理，我建议首先向您的 GeoJson 层添加一个引用

 <GeoJson  ref="geojson" data={this.state.geodatas} />

然后使用其参考访问地图

this.refs.foo.leafletElement.fitBounds(this.refs.geojson.leafletElement.getBounds())
